Wagering game having free spin feature with variable quantities of reel arrays

Summary by NHIP

Variable Reel Array Free Spins

The gaming system triggers a free-spin event where the number of displayed reel arrays changes between consecutive spins. The second spin array count is non-equal to the first, and arrays may feature variable symbol sets, reel weightings, line counts, or forms.

Abstract

A gaming system for conducting a wagering game includes at least one input device, at least one display device, at least one processor, and at least one memory device storing instructions. The instructions, when executed by the at least one processor, cause the gaming system to receive a wager for playing the wagering game, and trigger a free-spin event in which a plurality of free spins is awarded. For a first spin, a first number of arrays is randomly determined, displayed, and evaluated to determine whether an award condition is present. For a second spin, a second number of arrays is randomly determined, displayed, and evaluated to determine whether an award condition is present. The second number of arrays is non-equal to the first number of arrays. Any awards associated with each determined award condition are provided.

  1. 1
    A gaming system comprising:at least one input device;at least one display device;at least one processor;at least one memory device storing instructions that, when executed by the at least one processor, cause the gaming system to: receive a wager for playing a wagering game, trigger a free-spin event in which a plurality of free spins is awarded, randomly determine a first number of arrays for a first spin of the plurality of free spins, display the first number of arrays on the at least one display device, evaluate each of the first number of arrays to determine whether an award condition is present, randomly determine a second number of arrays for a second spin of the plurality of free spins, the second number of arrays being non-equal to the first number of arrays, display the second number of arrays on the at least one display device, evaluate each of the second number of arrays to determine whether an award condition is present, and provide any awards associated with each determined award condition.
  2. 11
    A computer-implemented method in a gaming system, comprising:receiving a wager in response to an input via at least one input device;in response to receiving the wager, initiating, by at least one of one or more processors, a play of a wagering game;representing the play, by at least one of the one or more processors, in a form of one or more reel arrays;randomly determining, by at least one of the one or more processors, a first number of arrays for a first spin of a plurality of free spins;displaying the first number of arrays on at least one display device;evaluating, by at least one of the one or more processors, each of the first number of arrays to determine whether an award condition is present;randomly determining, by at least one of the one or more processors, a second number of arrays for a second spin of the plurality of free spins, the second number of arrays being non-equal to the first number of arrays;displaying the second number of arrays on the at least one display device;evaluating, by at least one of the one or more processors, each of the second number of arrays to determine whether an award condition is present;and providing, by at least one of the one or more processors, any awards associated with each determined award condition.
